There you go. But to be fair, sometimes を can have a slight ‘w’-ish sound, depending on what sound comes before and on the person saying it. Unless I’m crazy and I’m hearing things…
When I was looking for that page, I was reminded again of how unintuitive the layout of TextFugu is, ugh :/ Had to trawl through a lot of guff to find it, since the pages of each chapter aren’t labelled in the contents. I can’t count how many times he’s fiddled with the design and layout of the site (instead of actually adding content) and it’s ended up worse and worse when you would have thought he be improving it. He really shouldn’t have split everything into separate pages – if everything for each chapter is in one big page like it used to be, you can easily Ctrl+F to get to the good bits, unlike this unlabelled mess there is now.
…another rant there, sorry folks :P
